PURPOSE:To ensure the enough breadth of relief part for skew setting in a laminating core by a method wherein projections for calking being contiguous to the slot are provided and the contiguous slots are made to be relief parts for the skew setting and the slots locating at the positions of the projections are made to be small. CONSTITUTION:Plural slots 3 are provided at the outer circumferential part of a rotor core 2, and projections 5 for calking lamination being contiguous to the slots 8 of a proper number within the slots 3 are provided. When skew setting are to be formed on the core 2 making the projections 5 as guides, the slots 8 are made to serve both for the relief parts of skew setting. Moreover the slots 7 locating at the positions of the projections 5 are made to be smaller than the other slots 3. By this way, the intervals of the slots 8 can be secured to have enough breadth to form the skew setting. |
